1994年3月29摘要本次調(diào)查的目標(biāo)是預(yù)測(cè)用于判斷液壓流體的磨損特性的葉片泵的磨損行為的一種數(shù)學(xué)工具的發(fā)展，根據(jù)ASTMD2882/DIN51標(biāo)準(zhǔn)方法389。相應(yīng)的數(shù)學(xué)算法的推導(dǎo)是基于合并后的描述和磨料粘著磨損現(xiàn)象發(fā)生在環(huán)和假說的剪切能在葉片泵連接，與隨機(jī)建模為二維各向同性隨機(jī)粗糙表面接觸領(lǐng)域。從環(huán)葉片摩擦接觸的決定性全面分析開始，為磨損計(jì)算，適應(yīng)具體的幾何，運(yùn)動(dòng)和摩擦系統(tǒng)葉片泵的負(fù)荷條件，被部分彈流潤(rùn)滑延長(zhǎng)列入數(shù)學(xué)模型的計(jì)算方法提供了必要的輸入數(shù)據(jù)。對(duì)于磨損性能的計(jì)算與試驗(yàn)結(jié)果的比較，對(duì)鉆機(jī)的一系列測(cè)試在B部分的敘述中會(huì)提出。不含任何添加劑的礦物油基潤(rùn)滑劑，采用排除添加劑的影響，不能在數(shù)學(xué)模型描述出來。在計(jì)算和實(shí)驗(yàn)之間的一個(gè)良好的定性關(guān)系隨著時(shí)間磨損過程和計(jì)算磨損質(zhì)量的量達(dá)到了。關(guān)鍵詞：數(shù)學(xué)模型;磨損機(jī)理模擬;磨損試驗(yàn)裝置，液壓葉片泵;彈流潤(rùn)滑;表面粗糙度簡(jiǎn)介在這項(xiàng)研究中，對(duì)于復(fù)雜的摩擦系統(tǒng)摩擦計(jì)的發(fā)展的一種新的方法的初步結(jié)果被提出來了。這個(gè)基本概念涉及到一個(gè)在實(shí)驗(yàn)的相互影響的過程中的的磨損計(jì)算的數(shù)學(xué)算法的起源，它可用于預(yù)測(cè)的摩擦磨損性能系統(tǒng)的力學(xué)模型可以模擬互動(dòng)的過程推導(dǎo)。這樣，一個(gè)額外的設(shè)計(jì)工具，實(shí)現(xiàn)了模型和原系統(tǒng)的磨損率的相關(guān)性創(chuàng)建。調(diào)查是執(zhí)行了用于判斷按照美國ASTM2882/DIN51389D型液壓流體的磨損特性威格士葉片泵V104的標(biāo)準(zhǔn)方法。在第一個(gè)步驟，一個(gè)以磨料和粘結(jié)磨損現(xiàn)象的描述剪能量假說為基礎(chǔ)，包括隨機(jī)粗糙表面接觸模型的數(shù)學(xué)理論，是適應(yīng)了現(xiàn)實(shí)的葉片泵摩擦磨損，延長(zhǎng)了部分問題彈流潤(rùn)滑和相應(yīng)的實(shí)驗(yàn)驗(yàn)證。這項(xiàng)研究的一個(gè)部分是專門用來對(duì)葉片泵的磨損行為的數(shù)學(xué)模型，并由此產(chǎn)生的算法驗(yàn)證;實(shí)驗(yàn)?zāi)p調(diào)查代表了B部分的焦點(diǎn)，這些都是與計(jì)算方法和在A部分所得結(jié)果進(jìn)行比較2．分析部落接觸威格士葉片泵V104C是一個(gè)每轉(zhuǎn)流量不變的泵。系統(tǒng)壓力導(dǎo)致了在轉(zhuǎn)子槽12個(gè)葉片的底部來封住由每一個(gè)葉片環(huán)槽盒和葉片的線接觸和環(huán)的內(nèi)部彎曲組成的單元。同時(shí)，所有其他的不同的和定期交變的流體壓力葉片面也都被強(qiáng)調(diào)了。一個(gè)在泵慣性力作用的所有準(zhǔn)靜態(tài)建模，考慮到環(huán)內(nèi)曲率，和切線曲率和裝載假設(shè)相關(guān)的葉片旋轉(zhuǎn)運(yùn)動(dòng)在文獻(xiàn)中有描述，從接觸力F的特征圖上，作為轉(zhuǎn)角度的功能可以得到，這由每次運(yùn)行和系統(tǒng)壓力所使用的葉片幾何形狀而定。由此可見，環(huán)內(nèi)彎曲可分為葉片環(huán)摩擦接觸（圖2）這與上環(huán)的磨損測(cè)量吻合分為四種不同的負(fù)荷條件區(qū)：在最大接觸面積部分（第二區(qū)），最高的線性磨損可以發(fā)現(xiàn)[2,3]（見B部分）3．?dāng)?shù)學(xué)建模3.1．磨損計(jì)算基本關(guān)系葉片和環(huán)形顯示聯(lián)合磨料和粘結(jié)磨損現(xiàn)象（圖3）。預(yù)測(cè)磨損計(jì)算現(xiàn)象的理論的基本概念在文獻(xiàn)中有描述?！?-6】。從磨損是由在具有相對(duì)運(yùn)動(dòng)的接觸表面的高剪切效應(yīng)引起的這個(gè)假設(shè)開始，基本方程如下：（1）在靜態(tài)磨損狀況中的線性方程組的磨損強(qiáng)度I可以得到，，其中包含具體的剪能量密度，可作為材料常數(shù)解釋，和真正的A區(qū)粗糙的接觸發(fā)生型剪切，為了確定這個(gè)實(shí)際的接觸面積，作為二維的基礎(chǔ)粗糙表面的描述根據(jù)文獻(xiàn)中的高斯領(lǐng)域。[7]是包含在建模。因此，隱函數(shù)關(guān)系被發(fā)現(xiàn)，它可以用來計(jì)算式中的表面比。（1）從赫茲壓力作用的研究摩擦接觸，由一個(gè)復(fù)雜的迭代過程每年在文獻(xiàn)中描述無潤(rùn)滑接觸。[6,8]。對(duì)混凝土結(jié)構(gòu)的函數(shù)F和c取決于身體的接觸（滑動(dòng)，滾動(dòng)）的相對(duì)運(yùn)動(dòng)。參數(shù)：u=通過它光譜表示了表面粗糙度的特性，也可以由表面的輪廓決定，塑性指數(shù)是彈性和塑性比例的量度。3.2擴(kuò)展到潤(rùn)滑接觸這個(gè)算法由摩擦計(jì)算的基本關(guān)系被成功應(yīng)用于無潤(rùn)滑摩擦學(xué)系統(tǒng)引出[8]。對(duì)于涉及數(shù)學(xué)模型中的潤(rùn)滑的第一概念在文獻(xiàn)中被開發(fā)。[8].他們是基于彈流潤(rùn)滑的經(jīng)典理論，以粗擦的微接觸的應(yīng)用，忽視了也有一個(gè)微膜隔開了這個(gè)連接機(jī)構(gòu)在微接觸的部分潤(rùn)滑情況下被打斷這個(gè)事實(shí)。因此用它們來做的磨損問題的實(shí)際計(jì)算不理想。他們?cè)谶@里延伸，包括在數(shù)學(xué)模型的以下假設(shè)。潤(rùn)滑導(dǎo)致了通過平均厚度為U的微膠卷的接觸機(jī)構(gòu)的分離，它可以依據(jù)通過（10）的表面粗糙度表示(3)其中u是根據(jù)兩個(gè)非常光滑機(jī)構(gòu)之間經(jīng)典的彈流理論的平均膜厚，可以通過[11]的風(fēng)向標(biāo)和環(huán)的線接觸決定（4）在部分位置的情況下，微膜在粗接觸時(shí)被中斷。一個(gè)塑料微接觸被解釋為純固態(tài)接觸，而對(duì)于一個(gè)彈性接觸表面粗糙度是通過微潤(rùn)滑膜疊加的。由于作為球型壓頭的粗糙的造型，微縮膠片的厚度可以由使用的球平面接觸彈流潤(rùn)滑理論確定，代表了隨機(jī)滑數(shù)模型。[8]
